Dear Experts,
Trying out computer authentication in my lab for a customer. Below are the steps done and issues observed.
1) Cisco switch is used. 3560 with advance ip services
2) AD 2012 is used
3) Dot1x for user auth is working flawlessly
4) Under wired authentication tab, i selected user or computer authentication
5) Now when the user signs out or locks the computer, i can machine auth being done.
6) Machine auth is successful and returned vlan is 100
7) Now below are 2 issues observed
7a) After sometime (not exactly sure) the line protocol of Vlan 100 is down. The light on the switch is green. I tried pinging the pc but it was not responding and when i saw on the switch the line protocol of Vlan 100 was down. I signed back in the pc, i got the prompt for dot1x, entered the user/pass and this time i the line protocol went up after sucessful USER AUTHENTICATION
7b) I signed out, and line protocol on Vlan 100 was still up. I pinged the pc, it was pinging successfully. I tried taking the RDP and it immediately brought down the line protocol on Vlan 100
Can someone tell me if this is the desired behavior for machine auth?
